Infrahyoid and Suprahyoid Muscles Anatomy

Infrahyoid and Suprahyoid Muscles Anatomy

Infrahyoid and Suprahyoid Muscles Anatomy

Sternohyoid muscle


1. Sternohyoid muscle

Origin: Manubrium of the sternum and medial portion of the clavicle.

Insertion: Body of the hyoid bone.

Action: Depresses the hyoid bone after swallowing.

Innervation: C1, C2, and C3 from the ansa cervicalis.

1. Sternocleidomastoid muscle

Origin (inferior attachment): This muscle has 2 heads of origin. The sternal head arises from the anterior surface of the manubrium of the sternum. The clavicular head arises from the superior surface of the medial third of the clavicle.

Insertion (superior attachment): Attaches to the lateral surface of the mastoid process of the temporal bone and the lateral half of the superior nuchal line.

Superior pharyngeal constrictor muscle


1. Superior pharyngeal constrictor muscle

Origin: This broad muscle arises from the pterygoid hamulus, pterygomandibular raphe, posterior portion of the mylohyoid line of the mandible, and side of the tongue.

Insertion: The muscles from each side meet and attach to the median raphe of the pharynx and pharyngeal tubercle of the occipital bone.
